Emma Watson, 138
If the fact that the actress who won people’s hearts as Hermione Granger in the Harry Potter series is also extremely intelligent should come as no surprise, it should be noted. Watson graduated from Brown University with a bachelor’s degree in English literature and an estimated IQ score of 138, according to his classmates. She is also an advocate for women’s rights and the founder of the United Nations Women’s campaign HeForShe, which encourages males to speak out in support of gender equality.

Conan O’Brien, 160
It’s not your typical talk show host when it comes to Conan O’Brien. He’s nothing short of a hilarious genius. O’Brien, who has an estimated IQ of 160, was valedictorian of his high school class and went on to get a degree in history and literature from Harvard University. Following college, he began his professional career as a sketchwriter for Saturday Night Live, where he participated in a number of his sketches. The rest, as they say, is history.
